Maduro said Friday that President Hugo Chavez could be sworn in by the Supreme Court later on if he's not able to take the oath of office before lawmakers on Jan. 10 because of his struggle with cancer, dismissing the argument by some opposition leaders that new elections must be called if Chavez doesn't take office as scheduled on Thursday.
